A leak-check obligation depends on factors such as refrigerant type, quantity and applicable equipment conditions. An energy-efficiency concern does not demonstrate a leak, and a leak-check record does not prove that the installation has a valid TM44 energy report.
What you need to know
- Identify the refrigerant and recorded charge before establishing leak-check duties.
- Use appropriately qualified personnel and verify relevant company certification for regulated work.
- Assess energy or maintenance concerns using measured data rather than automatic savings claims.
- Keep F-Gas service evidence and TM44 accredited inspection reports separate.
Which commercial equipment may need F-Gas review?
Commercial refrigeration, air conditioning and heat-pump systems can contain refrigerants regulated under the applicable F-Gas regime. The precise leak-check threshold and frequency depend on refrigerant details, charge, equipment category and exemptions; there is no universal annual rule.
Record the manufacturer, refrigerant designation, documented quantity and existing service logs. If any are unknown, ask an appropriately qualified specialist rather than inventing a regulatory schedule.
Understand official F-Gas leak-check dutiesEnvironmental and cost implications of refrigerant loss
Refrigerant emissions can have climate effects. Loss of charge or defects may also impair plant operation, but the financial impact depends on measured equipment condition, repairs, energy use and refrigerant characteristics.
Avoid guarantees of energy savings or a fixed cost reduction from compliance testing. Technical diagnosis and a documented baseline are needed to assess whether a repair or adjustment produces a meaningful benefit.
Investigate cooling energy costsCheck technician and company certification
F-Gas activities require the personnel qualifications relevant to the task; a business servicing equipment for other operators may also need appropriate company certification. Before agreeing attendance, verify contractor credentials, insurance and actual scope.
A TM44 air-conditioning energy assessor's accreditation is not automatically an F-Gas handling qualification. Equally, an F-Gas technician's certification does not authorise statutory TM44 reports by itself.
Review separate HVAC workstreamsWhat is different about TM44?
In England and Wales, qualifying air-conditioning systems with more than 12 kW effective rated cooling output generally require inspection by an appropriately accredited energy assessor at intervals not exceeding five years. F-Gas checks instead follow refrigerant-related rules.
These duties can concern the same physical equipment but yield different reports, records and responsible parties. Scotland and Northern Ireland require jurisdiction-specific consideration.
Read the TM44 inspection requirementsPlanning works across a refrigeration portfolio
Supermarkets, hospitality groups and managed estates can benefit from consistent site-level equipment records and separate service schedules. Plant access, operational criticality and certified specialist availability must be checked before grouping visits.
A procurement brief should specify whether the requirement is a leak check, diagnosed repair, preventative maintenance, a TM44 energy inspection or several separately priced activities.
Scope commercial refrigeration workRequesting a properly qualified contractor scope
Provide building locations, approximate equipment counts, refrigerant and charge where known, service history and any operating restrictions. A complete plant register is useful but not necessary for an initial enquiry.
Any firm quotation, specialist attendance and regulated report or repair must be confirmed against actual qualified capacity. A web enquiry is not an automatic booking or compliance decision.

This article does not authenticate a government register entry or establish the status of an individual building. Confirm the applicable national framework and the actual installed equipment before relying on a compliance conclusion.
England and Wales legal points are anchored in current government publications and the regulations. Technical applicability for a specific building still requires its actual system information.
